白花三角梅(Bongainvilla glabra Choisy cv. ‘Snow White’)原产于巴西,为紫茉莉科叶子花属的一种观赏花木。其花洁白如雪,花期长,既可作盆栽观赏,又可用于庭园绿化,因而深受人们喜爱。但是,在福州地区白花三角梅的种植远不如其他三角梅品种普遍,究其原因,除了气温较低和栽培上的因素外,更主要是扦插繁殖较难生根。为此,笔者于1985—1986年进行了生长素处理插条以及不同时期采用不同硬度(木质化或半木质化)枝条、不同扦插基质等试验,以期找出扦插繁殖的最适条件,为白花三角梅苗木的批量生产提供参考。
White Bougainvillea (Bongainvilla glabra Choisy cv. ’Snow White’) is native to Brazil and is a ornamental flower of the genus Mirabilis. Its white flowers such as snow, long flowering period, both for potted ornamental, but also for landscaping, so loved by the people. However, the planting of Bougainvillea grosvenori in Fuzhou is far less common than that of other Bougainvillea cultivars. The reason is that cutting propagation is more difficult to take root than low temperature and cultivation factors. To this end, the author in 1985-1986 for the treatment of auxin cuttings and different times using different hardness (lignification or semi-lignification) branches, different cutting media and other experiments in order to find the optimum conditions for cutting propagation, white flowers Cotton seedlings for the production of woody reference.
